The aim of this survey was to describe the trends in oral hygiene, gingival condition and dental caries prevalence in 13-14-year-old northern Jordanian school children.
A dental survey was conducted in 1999, similar to one carried out in 1993, utilising 10 schools (666 pupils) and 20 schools (1,695) with children of 7th grade, respectively. These schools were chosen by a simple random method from the five geographic areas of the city. All participants had dental examinations for oral hygiene, gingival condition and dental caries experience using the Silness and Löe plaque index (Pl.I), Löe and Silness gingival index (GI) and decayed (D), missing (M) and filled (F) teeth (DMFT) and surfaces (DMFS) codes, respectively.
Boys had higher plaque and gingival scores than girls in both groups. The mean Pl.I and GI scores of males and females were significantly higher in the 1993 survey than in 1999 (P < 0.05). Also, male and female children examined in 1993 had significantly higher caries experience, as measured by DT, DS, DMFT and DMFS scores than in 1999 (P < 0.01). No differences were found between M and F values of both groups. It is concluded that oral hygiene, gingival condition and dental caries has improved since 1993.
本次调查旨在描述约旦北部13 - 14岁学童的口腔卫生、牙龈状况和龋齿患病率的趋势。
1999年进行了一项牙科调查，类似于1993年开展的一项调查，分别选取了10所学校（666名学生）和20所学校（1695名学生）的七年级学生。这些学校通过简单随机方法从该市五个地理区域中选取。所有参与者分别使用希尔尼斯和勒氏菌斑指数（Pl.I）、勒氏和希尔尼斯牙龈指数（GI）以及龋坏（D）、缺失（M）和充填（F）牙（DMFT）及牙面（DMFS）编码进行了口腔卫生、牙龈状况和龋齿经历的牙科检查。
两组中男孩的菌斑和牙龈评分均高于女孩。1993年调查中男性和女性的平均Pl.I和GI评分显著高于1999年（P < 0.05）。此外，1993年检查的男童和女童，用DT、DS、DMFT和DMFS评分衡量的龋齿经历显著高于1999年（P < 0.01）。两组的M值和F值之间未发现差异。结论是自1993年以来口腔卫生、牙龈状况和龋齿情况有所改善。
